:Be 4it known that I, JoHNgC. Lisarnonsn,

'.eoitizen of the' United States, and-resident ofRoehester, in thecounty of Monroe and Statf New York, have 'invented oertain g new fand.useful 4lm' rovements in Wheel- Tires', ofjwliieh the ollowing is nspecification- 'A This invention relates towheel tires, and `consists inthe Vapperetns hereinafter de.

vseribedend claimed.

The'objeet of the invention is to provide e tire having a sectionalfelly, Whose tread surface is Composed of Iblocks of somewhatcompressible materiel, and 'which blocks are removalile-`and replaceable`i'ngease one is I l damaged. f

. tion of :l Wheel lisvi'ng-this invention applied I thereto, part belngbroken away tov show construction Fig. ,2 isl a front elevation of suche Wheel, part also being broken vaway to exhibit construction; Fig. 3isv anenlarged having one of the elamp'ingpls'tes removed,-

eross-seotionof a portion of the tire when in the operatlve position;Fig. 4 is an enlarged cross-section of the same part" of the tire,

y and one of Y'the tire blocks turned into positio'irfor removel orvreplacement of a tread eonpletetire section; Fig. Gis a section on`block; Fig. 5 is a perspective View of the the line 6 6 of Fig. 3; andFig. 7 is :L perspeetive View of a. moditloation.

In' lthe drawings, l is avwlieel hub, 2 are a series of spokesprojecting therefrom, and 3 is a. telly. All of these may be of theusual form, except thatthe :telly is made of suoli proper 'shape as Vtopermit two separable side plates 4, 4 to be clamped thereon in 'anysuitable way, as by the bolts On each side i of the felly is one of,lthe side plates 4, 'end bolts Apass through` the side plates and ellyend' fasten the parts together.v Between the side plates and outside thefelly'are fastened Sa.- series of tire blocks., which are so formed asto produ'ce sockets or box-likestructnres, open on the sides and closedat vthe ends, in which 'are fastened @series of the oompressible tire.bloks of' any suitable material, such as 1nd1a.-rubber.

Some of these Substances are ndepted for certain purposes better thanothers.

.In the formy of tire section herein shown,

thereis e bottom plate 6 having its ends turned down to fornil lianges7. On the outside of these flanges t end plates 8, 8, pro

jecting beyond thebottoin plete 6, and preferelolyv registering in.contour with .the

.flanges 7. Between the end plates are fastened t .e treed bloelrs 9,and through ythe l so end plates and through the tread blocks pass bolts10. These bolts maybe ofserew form,

and have heads of the ordinary screw rtype' set-ting in depressedsockets in one 'of the end plates and threaded toengege threads in theother end plete, so thatv on turning the bolt,

the end plates are 'pulled together against` the V outer surfaces of'the treed blocksA 9. It is.

preferable to provide means between. theend 1 'plates for preventingmovement :of the blocks along the bolts lll, and for this vpur. posee.portion of the bottoni plete d may be`V .n

bent up to 'form e rile ll, arranged .trams-4 versely, :is shown, andsubstantially parallel1 to the plaines of the end plates Send mid,-

tread blocks 9 may oe employed, having the rib l1 between them.

in this ease e'pnir of- By this method' off i construction, the treadblocks 9 are soxnewhat compressed et their bottoms by ineens `of thescrews or bolts 10 when all the parts areinthe position shown in thedrawing.

Through. the end plates and .through the lian es' in the bottom plate'ere registering per orations l2, so that the treed-bloolt holder,consisting of the end plates` 8 :rnd th/e bottom 'plete (l, may bestrung upon 'e ring 13 'arranged around the periphery of the 'felly 3snxlbetween the side plates 4. 'l

The efids'of the flanges Tend of the end lates^8 are so formed that whenthe 'ri ht-j.

land "side plete has been removed, W, ich` may be done upon removing'the nuts from.

the bolts 5, the tire section, consisting of 4the treed blocks and theseid holder, may loe .turned from the ordinary treadposition to e.position substantially at right :ingles thereto, es shown in Fig, 4,whereby theV I heads of the bolts 10 are nneovered, .and by unsorewingthe seme, the treed blocks 9,

may be removed for replacement if desired.

Qn turning any tire section again tothe po!Y s1tion shown in Fig. '3,and tightening the., ringl, the parte are tightened against the folly inan obvious manner. Any suitable Way of ti htening the ring 13 may beelnployed. vright and left hand n nt- 14` on the ends of the ring Meansere provided for preventing the,

tire sections from turnii'ig in the side plates 4, and for this`purpose' intermeshing irregw is one practical method 'of performingthis function.

larities inthe sides of the holder` and inthe side plates 4are"provided, as shown for instance in Fig. 3. On the inner side of eachi depressions 18` fittin of the side plates.' f henthe sidefplate 1sside plate there is a-groove 15, and a pro# jection 16, and on the sidesof the anges and of the end lates 8 (either or both) are rejections 17tting in the Asockets 1c, and l on the projection 1G removed, as in Fig.4,Y to permitthe 4independentpivotal-movement of one or more of the tiresections, the'ring y13 is free be sprung or moved to one side at therequired point suiciently to-permit the projections 17 on the' tiresections-in question to be disengaged from` the corresponding groove soas to permit the pivotal movemcnt. When f and before the latter istightened, the sec the tire sectionsare all strung on thefrod 13,

tions may be putin place against one of the side and t i theirregularitiesy 17 and 18 of the tire sections fit into ytheirregularities 15 and 16 of.

the side plate. Then the other side plate is putfupon the wheel with itsirregularities fitting those ontlie corresponding side the tlresections, the removed side plate `bolted firmly". kin place, and` theWheelv ready for use.'`

A type of tread this :type-of Wheel tire is shown herewith as nhavingfa-tread' face thatis depressed along the circumferentialcenterline, and having a part 9a 'on one side of said center-line that4vprojects farther outward than the ,part 9 In constructing the` on theopposite side. tire-sections, two `blocks 9 are placed together betweenthe plates 8, so that the part 9a on one block li ,adjacent `to the partk9h on the other block,and viceversa (Fig. 5).

The Wheel when assembled'with this type of tread bld'cks presentsv theappearance of Figs. 1 and 2. lt'may be readily seen that the surfacepresented to the pavement oiiers a greater numberof projections than yasmoothfaced tire, and said projections cooperate with theli projectionsof a rough .road and prevent slipping. Furthermore,

the interstices between the -parts 9 'give -room for the latter toexpand ongitudinally when compressed.

A surface more continuous but fiillyl ,as effective, 1s presented totheroad ifthe projections on adjacent blocks overlap each other laterally.,`Such a construction is shown in Fig. in which the lugs or prof seriesof tire sections 1n said groove; and` means for pivoting each tiresection to the plates 4 (the other being removed) en the rod 13 may betightened so that block adapted for nsein lvvlfieel".onfacirciini'erential axis, whereby,
